Nissan NOTE E11 CR14DE Engine: P0132 Lambda Sensor Error, Replacement, Voltage Readings & Symptoms

Hello, my father's car with CR14DE engine has a problem with error P0132. Today I replaced the lambda control probe with a new NTK, guided by this error and earlier voltage reading via ELM327 (over 1.2 V). Unfortunately, the new probe is unchanged - no voltage changes from the probe in the controller. The diagnostic scanner always indicates 1.275 V. The result of the voltage measurement on the probe signal cable is strange. The voltmeter indicates about 4.3 V on it and the voltage is unchanged.
Voltmeter measurement with a probe detached from the installation (I do not know if it is reliable), between grounding the signal and the signal, it showed about 0.8 V, while maintaining high revs. After releasing the accelerator, the voltage dropped to around 0.3 V, then returned to around 0.8 V again. I think the probe is working.

I will add that the car has a normal fuel consumption of 7.5-8 liters, no wave rotation etc., power is normal. The only symptom is the check control.

I have a suspicion about the controller - why such a 4.3 V voltage on the signal cable of the probe connected to the installation? I attach photos from the diagnostic scanner - please advise.

Attach to another tester, because I see on the parameters of 16 items that the parameters on the 2nd court shows what they should be on 1.

The reading from the 2nd probe sometimes changed after stronger gasification. The last photo shows this moment.

I have just read in Russian forums that there were cases of influence of 2 probes on work 1. Unplugging 2 probes caused readings from the regulator to return. In one person, replacing the 2 probes solved a similar problem, where the regulating probe hung at high voltage. I don't know what to think about it, it looks like some kind of damage in the ECU or in the beam. I currently do not have access to the car to carry out the test with the diagnostic probe disconnected (2).

I found similar symptoms shown in the video:

Hello, today the probe behind the catalyst was disconnected and the first began to give normal readings, the STFT correction revived. Measurement of the probe with a multimeter showed unwanted resistance between the signal cable and the heater circuit. In this case, the ECU interprets this incorrectly and informs about problems with the probe in front of the catalyst (P0132). A new diagnostic probe has already been ordered, unfortunately it turned out that the first probe was bought unnecessarily.

A similar problem was presented in this foreign forum:

After installing 2 probes I will inform you about the full success of the repair.

And how after changing the second probe? Because I have the same problem. Please and answer

This afternoon I will install 2 probe, but in my opinion it will be ok, because this 2 probe had obvious damage and caused confusion in the controller.


update:

Probe after catalyst replaced, all right. I have correct voltage readings from both probes.

Advice for others for the future - with voltage problems from 1 probe, start by disconnecting 2 probes and check if readings from 1 appear.
